FCCU Overview

Fluid catalytic cracking is an important step in producing gasoline in the refining process. Catalyst particles convert thick, long-chain hydrocarbons distilled from crude oil into more profitable, shorter-chain hydrocarbons like gasoline.

The catalyst and long-chain hydrocarbons are fed into the bottom of the riser line, fluidized, and blown upward at a high velocity, reacting as they rise. The now coke-coated catalyst is separated from the short-chain hydrocarbon gas products by two sets of cyclones in the reactor. The catalyst is fed into the regenerator section, fluidized by an air grid, and the coke is burned off the catalyst particles. The catalyst absorbs this heat; is separated by another two sets of cyclones; and is eventually fed back into the riser. The process repeats in the riser, using the absorbed heat to fuel the cracking reaction.

Frequently, on a turnaround of a fluid catalytic cracking unit (FCCU), refractory linings in the major vessels and transfer lines are found to have sustained significant damage. Repairs are time consuming and can be difficult to effect. The FCCU is made up of six major sections. This includes the reactor and regenerator, transfer lines, internal cyclones, slide valves, overhead lines, and the distribution rig.

With over 14 years of experience, RCS has patented and proven technologies to support the proper execution of FCCU outages from silica mitigation to independent anchoring systems (D-Bar & X-Bar).

Integrated Services

RCS is the premier provider of turn-key solutions and offers the following services, plus more, as part of our integrated approach.

FCCU

Fluid catalytic cracking is an important step in producing gasoline in the refining process. Catalyst particles convert thick, long-chain hydrocarbons distilled from crude oil into more profitable, shorter-chain hydrocarbons like gasoline.

SRU

The Sulfur Recovery Unit (SRU) is an extremely important unit for refineries or gas plants. Without it, there would be harsh adverse environmental consequences including severe acid rain, as well as lethal ground-level sulfur dioxide toxicity

Fired Equipment

RCS offers our clients true turn-key solutions for all of their fired equipment needs. We have you covered whether you require refractory repair, burner replacement, a complete retube, or anything in between.

Tanks & Terminals

A lot of midstream companies are mainly engaged in the transportation, storage and distribution of refined petroleum products and crude oil. These practices and facilities are often located in remote locations and servicing these locations can be challenging.
